SPECIFICATION forming part of Letters Patent No. 272,'728, February 20,1883. Application filed July 31, 1882. (No model.)

To all u'hom tt may concern Beit known that I, MosEs A. MARTINDALE, ofGeorgeto'wn, in the County of Clear Greek and State of Colorado, haveinvented a new and uselul Improvement in lrrigating Agri.

junction With the main and each other and upright pioesprojectingfromthe branch pipes, and provided with sprinkIing-distributers on theirupper ends, all as hereinafter more fully i set forth.

Reference is to be had to the accompanying drawings, forming part ot'this specification, in which similar letters of reference indicatecorrespondinr parts in all the figures.

Figure l represents a plan of a main and system of branches withdistibuting attachments in illustration of my nvention Fig. 2, avertical section in direction of the length ot' the main on the line xxin Fig. l; and Fig. 3, a vertical transverse section in part and uponalarger scale in direction ot' the lineyy, Figul.

A in the aeconpanying drawings indicates a nain pipe deriving its supplyof waterfrom a fissure or cavity in the side of a mountain, or which mayhe laid several miles up the mountain creels. and also several milesdown through the Valley land. Connected with this main pipe is anet-work or series ot'branch or lateral pipes, B, of smaller diameterthan the main pipe tor conducting the water to Whereever it may berequired for growing crops. Such system of pipes can cross all kinds ot'lands withinpnity,2tnl,it'necessa-y,tle nain pipe be bnred under theground when passing through valuable farms. or property, and the branchpipes be Iaid on the bare ground or otherwise, as desired. Monnted uponthese later-al pipes, at suitable distances apart, are

short upright pipes C, provided with sprink- I ling-distributers b ontheir tops, for soattering the water evenly and continuouslyin the formof sprays or showers over the land. Ooeks or valves d are fitted to themain pipe A at different points in its length, to restrict the supply ofwater to' certain localities, and the branch pipes B at their junctionwith the main pipe and with each other are similarly provided withstop-coclrs or valves d, for a. likeor analogous purpose.

The water-suppl v may in every case be a natural one, and thereforeiuexpensive, and as mountain streans are generally small but rapid,fiowing with' more water in the warm months, reservoirs of large areamay be constructed in 'the mountain gulcles for husbandland, besides it'desired, and in case of a surplus, furnishing towns and cities withwater or drivig motors connected with different meclanical industries.

` I am aware that a system of underground pipes radi-ating from acentral reservoir and provided with hydrants to which a hose is adaptedto be attached has heretofore been employed, and l am also awaretthat asystem ofpert'orated pipes laid upon the surface of the ground andradialing from a central reser Voir for irrigating purposes is not new,and I. therefore do not claim such inventions.

Having thus fnlly described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

The conbiation, with the main pipeA,leading from an elevated reservoir,and provided with valves d at suitable distances, of the branch pipes B,provided with the valves dat ther jnnction with the main and with eachother, and the npright pipes 0, projecting from the brancl pipes andprovided with sprinkltng-distributers b on their tops. substantially asand for the purpo e set t'orth.
